It should also be underscored that the deontic appearance of ordinary epistemic discourse seems to have a distinctively categorical flavor; that is, the phenomenology of our everyday talk and thought about duties, obligations, oughts, seems to imply the existence of categorical duties and obligations such as duties that are in some sense unconditional, that is independent of our psychology (desires, dispositions, beliefs,) and constrain what we ought to believe insofar as we are rational. For example, if a speaker utters, “You should believe that p” in an ordinary conversational context her statement would, typically, conversationally implicate that it is an (epistemic) fact of sorts that “You should believe that p.” A fortiori, the conversational implication is that anyone epistemically rational would be obliged to believe that p because it constitutes a categorical epistemic obligation (derivative of a corresponding epistemic fact).
